- Referring now to
FIG. 1 , there is shown a closure for aplumbing cleanout 10. Acylindrical plug 12 has afirst end 14, asecond end 16, and anexterior surface 18. There is aperipheral flange 20 atsecond end 16 ofcylindrical plug 12 which is adapted to limit the distancefirst end 14 ofcylindrical plug 12 can be inserted into theinterior bore 22 of theriser pipe 24, defined byinterior surface 26. A free floating “O”ring seal 28 engagesexterior surface 18 ofcylindrical plug 12 andinterior surface 26 ofriser pipe 24. “O”ring seal 28 is adapted to preclude fluids passing betweenexterior 18 ofcylindrical plug 12 and interior 26 ofriser pipe 24. Anoverlying cap 30 is adapted to serve as stop means for limiting axial movement ofcylindrical plug 12 relative toriser pipe 24. As shown inFIG. 1 , overlyingcap 30 is integrally formed withcylindrical plug 12. - Referring now to
FIG. 2 ,riser pipe 24 has aperipheral flange 40 such that overlyingcap 30 engagesperipheral flange 40.Seals 42 are provided betweenperipheral flange 40 and overlyingcap 30.Peripheral flange 40 has an innerconcentric skirt 41 and an outerconcentric skirt 43. Eachconcentric skirt riser pipe 24 with a different diameter. It is preferred that at least one ofconcentric skirts frangible connection 45, such that the concentric skirt which is deemed redundant is removable. As shown inFIG. 2 ,inner skirt 41 is used to attached toriser pipes 24 with smaller diameters, such as 2″, and can be removed by breakingfrangible connection 45 such thatouter skirt 43 can be connected toriser pipes 24 with larger diameters, such as 3″ without impeding flow. The connection may be made using an adhesive such as glue.FIG. 11 shows a largerdiameter riser pipe 24 installed withflange 40, andinner skirt 41 removed. - Overlying

Referring toFIG. 9 ,cylindrical plug 58 is shown withoverlying cap 30 andriser pipe 24 havingperipheral flange 40. Referring toFIG. 10 ,cylindrical plug 58 is shown withalternative overlying cap 48. - Referring now to
FIG. 12 , an alternative tocylindrical plug 12 is shown, whereinternal threads 62 are attached to the interior bore 22 of theriser pipe 24, such that acap 64 with acylindrical plug 66 havingexterior threads 67 corresponding to theinternal threads 62 may be secured by engaging theexterior threads 67 of thecylindrical plug 66 andinternal threads 62. As well, referring toFIG. 13 , an overlyingcap 68 with acylindrical plug 66 havingexternal threads 67 may be used, where thecap 68 is secured to theriser pipe 24 by aset screw 54. Referring toFIGS. 12 and 13 , seals 42 and 56 are included to keepsthreads - Operation:
- The use of this device will now be discussed with reference to FIGS. 1 to 13. Referring to
FIG. 2 ,closure 10 is installed withflange 40 attached to risepipe 24, where “O”ring seal 28 provides a seal betweenouter surface 18 ofplug 12 andinner surface 26 ofrise pipe 24. If desired, this connection can be supplemented bychains 38 as shown inFIG. 3 ornuts 37 andbolts 39 as shown inFIG. 4 to allow pressure release. Additionally, nuts 37 andbolts 39 can be tightened to restrict movement as shown inFIG. 11 . Referring toFIG. 6 , aset screw 54 may be used throughoverlying cap 48 to fixcylindrical plug 12 against movement as pressure increases. If alarger rise pipe 24 is used,appendage 34 may be used as shown inFIG. 11 and innerfrangible flange 41 may be removed. Referring toFIGS. 12 and 13 , an overlyingcap cylindrical plug 66 havingexternal threads 67, which engageinternal threads 62 in interior bore 22 to engage theoverlying cap riser pipe 24. - In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
- It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
